After a decade-long concerted effort, Hawaii has managed to more than double the amount of electricity the state generates from clean power, boosting it from 9 percent in 2010 to around 25 percent this year, according to a recent report. That’s a major achievement and will help Hawaii reach its first-in-the-nation goal of powering 100 percent of the islands’ electricity needs with solar and wind by 2045.

Roberts Hawaii — which operates close to 900 vehicles including tour buses, hotel shuttles and school buses in Hawaii — is not yet purchasing electric vehicles for its fleet. However, it has a pilot project with the state of Hawaii and the Honolulu airport to test out vehicles that use batteries, natural gas and hydrogen fuel cells.

The Director of Transportation for the National Resources Defense Council, Amanda Eaken, pointed to the electricity industry’s tight control of supply and demand as a possible tool for making transportation cleaner.

Solar Heaters

“The numbers of guests have doubled because thanks to the solar panels, the guest houses have functioning showers and warm water is made available for kitchen use,”says Marie Marku from Theth National Park in Albania.

Solar thermal systems use the sun’s light energy to heat water and can be especially efficient in heating water in areas where sunlight is abundant.  The technologies on the market are efficient and highly reliable, making solar power a simple, cost-effective, and sustainable means of heating water. Not only do solar heaters work well in areas where no other water heating options are available, it can also help to reduce operating costs and increase competitiveness. Many hotels in USA and the UK are using different forms of solar energy, with solar heaters as the most common form.

Using solar heaters can be particularly effective in Small Island States as most islands rely almost entirely on imported liquid fossil fuels for energy generation, with high costs of electricity. UNEP recently published a paper, “Solar Water Heating in the Tourism Industry with a Focus on the Caribbean Region,” highlighting the potential contribution of solar heating to reduce carbon emissions.

Facing increasing pressure to improve environmental performance and sustainability, using solar heating can be an efficient solution. Are you one of the businesses to use solar heaters for sustainability and efficiency purposes? If not, what are you waiting for?

Dart River Jet Safaris operates in one of New Zealand’s most picturesque mountainous wilderness areas, on the outskirts of Queenstown. While jet boating requires the use of fossil fuels in order to power the boats, this Maori owned and operated company leverages advancements in fuel injection technologies, and driver training.
